Inferior and precordial ST-segment elevation myocardial infarction due to large wrap-around left anterior descending artery occlusion

Abstract

Abstract Left anterior descending artery (LAD) occlusion normally develops into precordial ST-segment elevation; however, we describe a case of a 50-year-old man with inferior and precordial ST-segment elevation myocardial infarction that resulted from proximal occlusion of the wrap-around LAD perfusing the anterior and inferior wall. We performed early and prompt reperfusion and were able to save the patient without any complications. A wrap-around LAD perfuses a large myocardial area; therefore, this type of coronary occlusion causes severe myocardial damage and has a poor prognosis. The rates of new-onset heart failure and heart failure rehospitalization are also high. Simultaneous inferior and precordial ST-segment elevations on electrocardiography suggest acute myocardial infarction with a wrap-around LAD lesion, which requires prompt revascularization. More careful medications for heart failure and follow-up should be also required even after discharge in such case.
